To all whom it may concern." 1 2- Be'it known that I, WINTHRoP Form, a citizen of the United States, residing at ,Torrington, in the county of Litchfield, State of Connecticut, have invented certain new and useful Improvements in Gasolene- Meters; and I do hereby declare the fol lowing to be a full, clear, and exact description of the invention, such as will enable the dial hand, caused by the liquid slushing around in the tank.

1 A further object of the invention is to improve the general construction and improve the efficiency of indicating gages of this type.

With these and other advantages in view the invention resides in the novel combination, formation and arrangement of parts more fully hereinafter described, illustrated in the accompanying drawings and particularlypointed out in the claims hereto appended.

Reference is had to theaccompanying drawings, wherein similar characters of refarts erence designate corresponding throughout the several views, an which Figure 1- is a side elevation of the improved device attached to the gasolene tank of an automobile and having its dial portion affixed to the dash board. Fig. 2 is a front elevation of the device. Fig. 3 is a vertical longitudinal sectional view through the device and Fig. 4 is a perspective view of the indicating arm.

Referring more particularly to the drawings, wherein is shown a preferred form of the invention, 10 designates the gasolene tank-and 11 the dash board of a conventional type of automobile.

M invention includes a tube 12 extending vertically from that end of the tank adjathe bottom thereof. At the upper extrem. ty of the tube, there is provided a dial cas mg 13 WlllCh is aflixed to the dash board.

This dial casing carries on its outer face a plurality of symbols 14 for indicating, in conjunction with the dial hand 15, the amount of gasolene contained .in the said tank 10. This dial hand 15 comprises the indicating arm 16 and an inwardly and lat erally directed extension 17 which extends into the casing, the lateral portion of said extension being ivoted thereto and the inwardly directed portion slidable in a slot- 18 formed in said casing.

For providing means to oscillate the dial hand 15, a piston 19 is slidably disposed in the lower end of the tube 12. Slidable in the upper end of the tube is a second piston 20. A coil spring 21 is disposed in the tube between the two pistons and has its extremities attached thereto. It will thus be seen that there has been provided an efiicient float which includes the air space between the pistons 19 and 20.v The function of this peculiar structure above described is that by providing the coil spring 21, oscillatory motion of the piston 19, caused by the slushing about of the liquid in the tank, will be taken up thereby and not transmitted to the iston 20, although an upward or downwar movement of the piston 19, caused by changing the level of the liquid will be transmitted to said piston 20.

For oscillating the dial hand 15 upon movement of the piston 20, a connecting link 22 has one end secured to the piston and the other end secured to the free extremity of the extension 17.

It will thus be seen that. there has been provided a simple and efficient type of gage which will fulfil all of the objects heretofore disclosed.

What is claimed is 1. A gage of the class described, comprising the'combination with a receptacle of a tube affixed thereto and terminating at its lower end at a point adjacent the bottom of said receptacle, a piston slidable in the lower end of the tube, a second piston slidable in the other end of the tube, resilient means connecting the said pistons, a dial, a dial hand carried by said dial and operating means connecting the dial hand and one 0 said pistons. j

In a a 4 ea j cent into. the tank and terminates at a point adjacent 2. A gage of the class described, comprising the combination with a receptacle of a tube affixed thereto and-terminating at its lower end at a point adjacent the bottom of said receptacle, a piston slidable in the lower end of the tube, a second piston slidable in the I: per end of the tube, a coil spring dispose within the tube between-the plsto'ns and havin its extremities attached thereto, a dial carried by the upJJer extremity of the tube, a dial hand carrie by said dial, a piv oscillating the dial hand.

In testimony whereof, I alfix my signature, in the presence of twowitnesses.
